IMPROVEMENT IN WATER-METERS.

Specication forming part of Letters Patent No. 170,895, dated December7, 1875; application iiled May 1, 1875.

To all whom it may concern Be it known that I, FREDERICK PHILIPPI, ofSt. Louis, in the county of St. Louis and State of Missouri, haveinvented a new and useful Improved Water-Meter, of which the followingis a specification :A

This invention relates to that class of liquidineters which work ormeasure the fluid by means of bags. The water, in filling one bag,expands it, and in doing so con tracts by'emptying' the other, and viceversa, and it is this emptying of each bag measured by a registeringdevice that determines the quantity of the liquid passed through theapparatus. The features or means accomplishing this operation are theinlet-pipes with the bags, and their further connection to a tiltinglever that controls the valves in each bag, all arranged to operate inthe manner now to appear.

Oi' the drawing', Figure 1 is a longitudinal section through theapparatus, with valve parts also shown, Fig. 2 being a top plan of Fig.l, showing, besides, the pipe arrangement.

My meter is surrounded by a suitable casing filled with water, so as t'oequalize the pressure on the apparatus.

A is the inside framing, upon which the operative parts are mounted. Tothe sides of the frame A the bags B B' are secured in a water-tightmanner. These bags can be of cloth, leather, rubber, or similarmaterial. I divide the bags by a Water-tight partition, b, which formsthe two compartment-bags B B',

` the object being to allow the liquid toiill one of said bags While theother empties. The partition b at top carries a roller, C, which runsalong the lower edge of a tilting lever. Forming part of the bottom ot'the partition b is a truck, C', having rollers, which run along on topof a brace-rod, c, (see Fig. 1,) the object ot' the rollers above andbelow being not only to guide and ease the motion of the bags to andfro, but specially to utilize the movement ofthe bags to control thevalve attachment, which further controls the inlet and outlet of theliquid in its passage to and out from the meter. Hence this valveattachnotched arms d2, which are pivoted to the brace-rod d. (See Fig.l.) d3 are springs which hold the arms d2 against the stops. The arms d2project below the lever, as shown in Fig. 1, so as to be operated by thecontact of the upper roller C. The outer lever ends have springs e aboveand springs el below', and connect by valve-rod c2 to a pivoted valve,e3, as clearly shown in Fig. l. E E' are the supply-pipes. All saidpipes enter the apparatus where t e valve e3 controls their openings.

The position of the meter being as shown in the drawing, the operationof the apparatus is as follows The valve to the' right opening thesupply-pipe E', the iiuid enters, filling the bag B', and by forcecausing the movable partition b to move to the left, while at same timethe water is being forced out of the bag B through the discharge-pipe F.The bag B keeps on discharging until, by the 'contact of the roller Owith the left-hand arm d2, this is thrown out of engagement, causing theopposite lever end to become engaged with the arm d2, which reverses thevalve e3, and the Water then enters through the opposite supply-pipe Einto the empty bag B, illing the same, and at the same time emptying thebag Bl through the disch arge-pipe F', the roller C still moving to theright, until, by contact with the arm d2, the operation of th'e valveIattachment is reversed, and thus one bag is filling while the otherdischarges.

Any-suitable registering device is attached to the apparatus, by meanswhereof the number of discharges ot' the iuid from each bag is keptknown.

What I claim is- The combination of the bags B B', movable partition b,carrying-roller C, truck C', the tilting lever D, having stops d', armsd2, and valve attachments e3, with inlet and discharge pipes E E' F F',all arranged to operate in the manner and for the purpose set forth.

In testimony of said invention I have hereunto set my hand.
